Table 3.

Values of the total and component attributable risks and their standard errors from two different models for a case-control study, each with four exposure categories, from Poisson and logistic models. For the third and seventh columns, a general purpose MLE program was used. In the third and seventh columns the method of Greenland and Drescher (1993) was used with the logistic model. For the fourth and eighth columns, the standard logistic model was used.
